Let me rephrase that -  spinternalerror01 fails on both smp and non-smp
builds. I cannot see how the test could work on leon3. The test has a
custom boot_card() function that does not call
rtems_initialize_executive(), so the AMBA plug&play is not scanned and
no UART driver is registered. There cannot be any output unless a UART
driver is registered. On erc32 and leon2, the UART drivers are hardwired
and do not need rtems_initialize_executive(), so it works there. Maybe
the test should be marked as invalid for leon3 ...?
